IAV design study plane

An aircraft developed as a test platform: a way to compare aerodynamic simulation methods before applying them to the next design.

The question

How can the team make its CFD workflow repeatable? This project provides a common aircraft geometry for comparing simulation settings and aerodynamic behavior.

A useful baseline

The modular, high-aspect-ratio wing configuration supports studying induced drag, wingtip vortices, and stall behavior. A shared baseline makes differences between simulation approaches easier to examine.

Simulation choices

The workflow considers k-epsilon and k-omega SST turbulence models, alongside mesh refinement around the leading edge, boundary layer, and wing-fuselage junction. The aim is to separate changes caused by the model from changes caused by the mesh.

Designing for the next project

The platform supports a common approach to geometry, boundary conditions, and solver selection. It is a tool for evaluating subsequent aircraft concepts with more consistent assumptions.
